Fuzzy logic is the reasoning methodology that has grown out of a branch of formal mathematics known as fuzzy set theory. It has been used to handle uncertainty in rule-based software systems, where it is particularly effective in capturing qualitative aspects of human reasoning. Many applications using the fuzzy logic inference mechanism for ill-defined expert systems have been successfully demonstrated in Japan and Europe. In spite of its apparent potential, this unique method has not been extensively used in NASA applications. A general lack of confidence in the use of this powerful technology stems from the lack of adequate tools to develop systems. This project should result in user-friendly, easy-to-use, expert-system shells with this new paradigm embedded in the existing expert system shell, CLIPS.
Potential Commercial Applications: This software tool can be effectively used to construct expert systems for vehicle and process control, pattern classification, financial decision making, sales prediction, industrial design, and psychology.STATUS: Project Proceded to Phase II
